Ultra-tough and super-robust hydrogel constructed through carbon dots induced crystallization domains integrated orientation regulation based on “pinning effect”
Abstract
In
this
study,
we
present
a
novel
strategy
in
which
carbon
dots
(CDs)
are
employed
to
induce
the
formation
of
crystalline
domains
and
further
fabricated
super-strong
hydrogels
with
high
crystallinity,
distinct
anisotropic
structures
dense
networks
based
on
“pinning
effect”,
specifically,
CDs
act
as
nanofillers
heterogeneous
nucleating
agents.
As-prepared
exhibited
exceptional
swelling
resistance,
ultra-high
tensile
strength
(156
MPa)
toughness
(225.2
MJ
m−
3),
surpassing
most
other
tough
polymers,
including
natural
tendons,
plastic,
synthetic
rubber
artificial
spider
silk,
etc.
Notably,
hydrogel
can
support
loads
up
approximately
1.5×105
times
its
own
weight,
highlighting
their
load-bearing
capacity.
Moreover,
be
generalized
adapted
environments
more
stringent
mechanical
loads.
This
work
not
only
offers
new
insights
into
fabricating
ultra-robust
but
also
lays
foundation
for
design
development
smart
materials
underwater
sensing.
